Referring more paitiuiai'ly zo the drawiiig's, my invention ifesi'fies in the combinetion of e. pluifaiity of spring forks l ilteimately disposed. between the imiei'fi'im 2 :moi the outer tread 3 of any automobile o1' other vehicle wlieei represented :is o. whole by lThe Spring fori l 'oiiiied substantiuily ii-si'uiped in -eiose sectie :imi one erm of @zich forli iS turned outwardly soo- Stimtieliy :it righi'. iaiiglee so ne to form the shook 5 adopted to engage the side of the i-im 2; while :t iienge (i extends forwardly beyond the shank 5 sind adapted to engage the bottom of the iim A bolt hole "i" piorcee the sbonk und rei-cime the ooit 'o' wliioll i .sees liorizoni'eily through the rim 9. and Secures "he spring fork i iigiiily in place upon rim The oth/oi* :m11 oii the. :spring fork l ie likewiee turned mitweieily und again fofwercily so as te oi'ix. e ioni:-

Upon the outer Siiizioe of the trend piiite l0 is pennmieiitiy attached. the tiie pietel2,-same being forii'ied with the ii'itei'ioily iispooed iont iodine! groove 125, seid groove being adopted to cooperate with Seid slots, il and il vliioii` open salici groove 3 oz tiie purpose-of holding' Spring forks l in piace by means of the linuokie 9 interlocking through saisi tiead piee i0. as aforesaid.

it Wiil noted that the spii i' s zii-e .flupiieotee et one miotli if, ond tout they 15 bearings of the Shanks and the flanges 6 be braced between the tread plate and the tire plate 12, which will prevent rat` 'may be desired, and as shown in the drawings. It will be noted that instead of constructing the 'spring forks l'i'n integral formation as shown in Fig. 2, same may be built up'of aseries ofA leaf` springs 14, as shown in Fig. 8. This latter construction will give greater resiliency and life to the spring forks 1. The spring forks may lbe of sutilcient Width to correspondingly widen the againstthe'rim Ztoguard against longitudinal displacement of said spring forks under the stress of the forward or backward motionf of the vehicle. To further guard against this longitudinal stress, longitudinally disposed, torque straps 15 may be provided-t0 connect the inner and outer rims'at spaced points, so that said torque straps Will transmit the longitudinal strain of the revolvinginner rim to the outer rim.

" .If desired, the semi-'circular forks may be joined integrally in sets of two so as to form complete circles as shown in Fig. 7. Also, wherethe semi-circular or U-shaped forks are used the arms thereof designed for engagement with the inner rim may be inclined si'dewise so that any two oppositely disposed forks may be bolted to the inner rim by means of one bolt, as shown in Fig. l1.

It Will be noted that I, have herein pro vided a resilient wheel well adapted for the purposes intended and as enumerated in this specification, and it is understood that I may vary from the exact method of construction here laid down, in minor details, so

' as best to produce 'my improvement in a.

practical and commercial form, as defined in the appended claims.

What l claim to be new and atentablees:

l. A resilient Wheel vc'ompr1sing a hub; an inner rim; an outer rim having a lock plate on its inner surface; means for connecting the hub and inner rim; a plurality of U-shaped spring forks each having one extremity bent, widened and bored to form a shoulder adapted to be bolted to the inner rim and having the other extremity bent to forma knuckle adapted for locking engagement with the lock plate of the outer rim; said spring forks being set in alternately reversed relation to one another; and a plurality of torque straps connectingthe inner and outer rims.

2. A resilient Wheel comprising a hub; an inner rim connected to said huir; a plurality of spring forks having one end recessed to form a bottom and side bearing against said rim, the side bearing ends being also 'deected sidewise so that the ends of forks alternately arranged on opposite sides .of the rim willl be alined across said rim; and an outer rim connected to said inner rim by said spring forks.

3. A resilient wheel comprising a hub ;-an

inner rim and an outer rim; means for connecting the hub and inner rim'; a plurality of semi-circularv spring forks connecting the inner and outer rims, said forks having their arms designed for engagement with the inner -rim deflected sidewise, so that as sembled in alternate and reversed relation transversely across the wheel, one bolt will suiiice to secure two forks to said inner rim.
